The song begins with a single plucked "A" note which builds in feedback until
the string is vibrating hard enough to cause a feed-back-fuzz.
The "I Feel Fine" riff (repeat as needed):

D7 C G

This is obviously just the same riff moved down to different positions.
This is the main riff of the song.
In fact most of the song is just this riff played at the three different
positions (G,C,D)
The only different bit is :
G Bm C D7
I'm so glad that she's my little girl
G Bm C D7
She's so glad she's telling all the world
The solo is over the G/C/D riff.
